To all whom it may concern:

Be it known that 1, WILLIAM E. WINE, a, citizen of the United States, residing at Toledo, in the county of Lucas and State of 'Uhio, have invented certnin new endnselul Improvements in Ger-Door Locks, of which the following is u specification.

This inventionreletes to door-locliing'devices for reilwey wrs or the like end hes for its object to provide improved means "for holding the doors in closed position, the orrangern'ent being such us to he rendil released when it is desired to open the cors.

Another object is to provide simple means for lochngfor unlocking n plurnlity oil doors at one end the sometime by means of e coin-.

noon mechanism. With such objects end others in view the invention consists of the 0 u I [1 formation, combination and arrangement 01 ports es will he herein'descrihed and perticulsrl cleinced.

In t' e accompanying drawings which show u preferred embodiment of the inven- 'tion, Figure 1 is a side elevntionsl view of e portion of it our body, this view showing f particularly the lower corner of the hopper portion of s our of well lZIlOWIl type. Figure 2 is a fragmentary e'levntional view of the some; this view being seen in the direction of the arrow 2, Figure 1. Figure 3 is s transverse sectional view taken: through the {hoppers oi one end of such it our, the

' view being taken approximately on n planeindiceted by the line 33 of Figure 1 end showing the locking mechanism of the present invention in its relationship to the our doors end other portions'o'f the car body.

Figure 4: shdws, in a view similar to Figure- 3, a modified application of the mechanism, wherein each of the pn'ir of doors is locked independently and at the center as well as st the sides of the cor. Figure 5 is adiagrammutic View of the side of a car, showing the general arrangement of doors such as are used for reference in Figures 1 to 4.

Referring to these drawings, the side of the car or the side of-the hopper is denoted by the numerel'l, the bottom of the hopper being denoted-by the numeral 2. The hopper as shown is that commonly employed on cars of the twin hopper type, having the hopper door 2 inclined to form echute for the discharge ofthc contents by gravity.

Such hoppers are ordinarily provided et each end of the car and there are customarily two such hoppers et eech end arranged side by side es indicated at 3 end, 4 in Figure and st 5 and 6' in Figure h The inner sides of these hoppers ere defined by hopper sheetsfi', with an intervening space which so 4 customarily results from the center or draft sill construction of the our.

Each of the hoppers is closed by means chute plate 2. The doors ere hinged. or pivoted along their upper edges at 9 to the car body, the free edges 10 of the doors being arranged to swing away from the, we open ends of the chute plates 2 when the doors are to he opened. No special mechenism is provided for the mechanical swinging of the doors intoiclosed positions as it has been found that if the doors ore properly to fitted they can be swung by hand' it is the object of the invention to provide im- ,proved means for locking the doors often 3 they are closed manually and tothis ends bracket 11 1s secured to the side of the hopso per by means of rivets 12. This bracket hes a, staple or other hook-engaging member 13 utilized to it and the door carries a pivoted locking member in the form of a hook 14, which is arranged to latch over the so staple 13 when the doors are pulled shut, thus holding the door in closed position without the intervention of any unnecessary parts When the hooks let are in holding poslt'ion the dog 15 whichis made in com no shepe end pivoted to the bracket 11 by moons of e rivet 16, is rotated about its pivot so asr to contact the point 17 of the hook end preventthe accidental release of the same. Formed integral with the'cam 15 and on the opposite side of the pivot 16 is on extension 18 which is provided for forcing the eccentrio cam into or out of hard engagement with the point 17 of the hook 14.

The present device 'isso arranged that a. lot plurality of locking hooks may beso erranged transversely of. the car or otherwise in line with each other, that they may be operated together from a single point and as a single unit. Thus in Figure 3 one hook outfit is shown along each side-of the car with a bracket and staple for each hook. The hooks are connected by a shaft 19 which extends across the car from side to side,

- is carried in tion when mounted upon the shaft as shown.

Accordingly when the shaft is rotated from ofdoors for the pair of hoppers at one end.

of the car. The shaft thus serves as an ali ing and supporting means for the doors an prevents them from bulging or bending due to the pressure ofthe lading againstthem.

Such doors are often provided with outturned' marginal flanges such as shown in the drawings in order to'stifi'en the ed es of the doors. Because of the presence o such flanges it is necessary that the shaft 19 be spaced away fromthe backs of the doors a 'suficient distance to allow it to pass uninterruptedly and without weakening over the outermost edges of such flanges, inasmuch as the ."shaft replaces the ordinary doorsupporting beam or stifiener. This arrangement of the shaft, considered asa stifi'ener, is one of the objects of the invention.

' In order that the shaft may beproperly carriedupon'the doors, brackets 22 are afiixed to the doors by means of the rivets 23, these being afiixed to the faces of the door plates away from the cavity of the car. These brackets have cylindrical apertures which accommodate cylindrical spools 24 which are fitted upon'the shaft 19. The spools 24 have square apertures for their fit upon the shaft 19, hence the rotation is effected by the spools 24 revolving within'the brackets 22. Each s 001 24 has a collar 25 of slightly larger dlameter than the bore of the bracket 22 and these collars overlie the. hubs of the brackets to prevent endwise movement of the shaft 19 and'the parts carried by it. The collars of some of thespools are arranged to prevent movement in one direction and the collars of others to prevent movement in the op- I posi-te direction. Cotter pins 26 are applied in'holes suitably drilled in the shaft 19 to retain the collars and the hooks against movement on the shaft. An extension 27 is formed upon the hook 14 in a position on the opposite side of the axis thereof from the locking face of. the hook'and this may be utilized for forcing the hook out of engage-- ment with the "staples in case a wrench is not available for the shaft 19.

In the modification shown in Figure 4 two hooks are used for'each of the doors at an end of the car, there being hook outfits on the inturned' faces of each of the intermensane? diate chute hopper sides 7. One shaft 28 extends inward from the side. of the car to near the center and each such shaft carries a pair of hooks 14, one near each end of the shaft. In this manner the door8' may be locked along each edge instead of along one edge as in the arrangement shown in Figure 3. The arrangement of the bracket .11 with the staple 13, as well as of the brackets 22 and spools 24, is the same as previously described for the construction of Figure 3, the only difierence being thatthe two hooks on a common shaft in this case serve only one door whereas -in the receding case they served a pair of doors. he dogs 15- for the interior hooksin this arrangement may or may not be used. When they are used a 2. In a door mechanism for railway cars,-
